Abstract

The invention provides a curing pretreatment method for improving spinnability of hemp fibrils. The method comprises the following steps: selecting hemp fibrils with modal length of 27.5-30.0/mm and fiber number of 2900-3100/Nm; spraying an oil feeding and moistening softening and penetrating agent on the hemp fibrils, wherein the weight percents of the oil feeding and moistening softening and penetrating agent and the hemp fibrils are 6-8%; keeping the hemp fibrils with the oil feeding and moistening softening and penetrating agent in a sealed way, carrying out moisture curing for 70-120 hours at the temperature of 23-28 DEG C, controlling the moisture regain of the hemp fibrils between 12% and 15% and turning over the hemp fibrils up and down at least once during curing; loosening the hemp fibrils and removing impurities and short fibers to ensure the impurity ratio and short fiber ratio of the hemp fibrils to be less than 13.1/% and 27.2/% respectively. The method has the beneficial effects of obviously reducing the noil fiber rate of the hemp fibrils, improving the flexibility, ensuring the fibre strength required when the hemp fibrils are spun and improving the spinnability of the hemp fibrils.

Description

Technical field: [0001] The invention relates to a hemp fibril pretreatment method, in particular to a hemp fibril health-preserving pretreatment method that can improve the spinnability of the hemp fibril and facilitate subsequent processing. Background technique: [0002] Hemp fibrils are fibers obtained from hemp hemp or hemp leaves. It is a bundle of fibers with thick fibers, high rigidity, no natural curl, small cohesion between fibers, and poor length uniformity. Because there are groove-shaped cavities inside the fiber, the walls are many voids, and contain pyrimidine, purine and other anti-mold and antibacterial substances, the hemp fibril textiles have the advantages of crispness, coolness, high strength, fast moisture absorption and dehumidification, and not close to the body. It has anti-corrosion, anti-bacterial, anti-ultraviolet, anti-static and other characteristics. Therefore, in recent years, the sales of hemp textiles in developed countries such as the Unit...
